FUEL SYSTEM - FIVE-TANK INDICATOR FQIS

CONVERSION OF 1420KID1-1 AND 1421KID1-1

BY REPLACEMENT OF REAR CONNECTOR NEOPRENE SLEEVING WITH SILICONE SLEEVING

1. PLANNING INFORMATION

A. Effectivity

(1) Aircraft affected: Airbus A300-600, A300-600ST and A310 

(2) Unit affected: Multi-Tank Indicator FQIS to Mod. State 00, 01, 02 or 03 

(3) GE Part Numbers: 1420KID1-1 and 1421KID1-1 

B. Reason

(1) Condition conversion corrects

The neoprene sleeving on the rear connector has the potential to degrade and 

fragment when used in higher temperatures.

Revision No.1. Jul 23/08 Page 2 

GE Proprietary Information – subject to the restrictions on the cover or first page 

(2) Extent condition encountered

One known occurrence to date 

(3) Expected benefits of conversion

Product improvement. The replacement silicone sleeving has a higher thermal 

tolerance. 

C. Description

Electrical connections to the indicator are by way of two 19-way connectors (PLA and PLB) 

fitted to the rear of the unit. Every wire that terminates to these connectors should be insulated 

by a single silicone sleeve. Due to an error in engineering stores, a batch of neoprene sleeves 

was accidentally mixed with stock of silicone sleeves. Although almost identical in appearance 

(both are pink), the thermal tolerance of neoprene sleeving is significantly lower than that of 

silicone sleeving. An unknown number of units were manufactured using the incorrect 

sleeves. Given it is not possible to identify if a sleeve is silicone (correct) or neoprene 

(incorrect), for safety reasons in all instances where it is possible the incorrect sleeving was 

fitted, each and every sleeve will need to be replaced. To further aid the identification of the 

correct type of sleeve the replacement sleeves are White. 

Once this work has been carried out a new part number label is fitted to re-identify the unit in 

accordance with paragraph 1.H below. 

D. Compliance

All units on return. 

E. Approval

The technical content of this Service Bulletin has been approved under the authority of the 

EASA Design Organisation Approval N° EASA.21J.031. 

F. Manpower

The incorporation of the conversion only (disassembly/assembly) will take approximately 3 

man hours excluding testing. 

G. Material and Availability

The materials kit, part number 1420KID-28-469, is currently available and is free of charge. 

For details of the contents of the materials kit, refer to paragraph 3 of this Service Bulletin. For

2. ACCOMPLISHMENT INSTRUCTIONS

WARNINGS: FAILURE TO FOLLOW THE APPLICABLE INSTRUCTIONS GIVEN IN THIS 

PUBLICATION AS AMENDED BY GE AVIATION REVISIONS MAY ENDANGER 

SAFETY. 

NOTES: All references are to Component Maintenance Manual 28-47-68 unless otherwise 

stated. 

A. Embodiment Instructions

(1) Refer to DISASSEMBLY and read the CAUTION above paragraph 1 then note the 

requirements of paragraphs 1 and 2. Proceed then to carry out the instructions 

detailed in paragraph 3.H. to remove the two electrical connectors PLA (120) and PLB 

(125). Discard all pink binding sleeves removed during this procedure. If undamaged 

it is not necessary to remove any wire identification sleeves that are fitted to each 

wire. 

(2) Examine both electrical connectors for corrosion, overheating and bent or damaged 

pins. Any evidence will require the replacement of the relevant connector. 

NOTE: Although not currently listed in the CMM it is recommended that item (120), which is currently 

item part number 40-743-3144-00 is replaced by item part number 40-743-3135-00. Similarly 

item (125), currently item part number 40-743-3144-01, should be replaced by item part 

number 40-743-3135-01. The current items have pin-tail connections, the recommended items 

have solder bucket connections and are significantly quicker to fit. 

(3) From the conversion kit select the following items: 

(a) 32-off White Silicone Sleeves, 1.5 mm x 10 mm, part number 30-784-529-01. 

(4) Refer to DISASSEMBLY and proceed as follows: 

(a) Do the procedures in paragraphs 3.A., 3.B and 3.C as necessary to gain 

access to the Power Supply Board Assembly (50). 

(b) Remove and retain the screw (55) securing the earth solder tag (60) on the 

corner of the Power Supply Board Assembly (50). 

(c) Remove and discard the pink binding sleeve insulating the earth solder tag 

(60) on the corner of the Power Supply Board Assembly (50). 

(d) Unsolder the wire from the earth solder tag (60). Slide a White Silicone 

Sleeve onto the disconnected end of the wire. 

(e) Solder the wire onto the earth solder tag (60). Reposition the White Silicone 

Sleeve so that it insulates the earth solder tag (60). 

(f) Position the earth solder tag (60) on the corner of the Power Supply Board 

Assembly (50) and secure in place using the retained screw (55). Use the 

specified locking compound on the screw thread.
